Arduino's ::delay() is implemented in core_esp8266_wiring.cpp alongside millis(). Because __delay calls millis() within the same compilation unit, --wrap=millis can't intercept that intra-object reference, which prevents the linker from garbage-collecting the original millis body (~80 bytes of IRAM). Replace esphome::delay() with a simple yield loop that uses our fast millis() accumulator. This has the same behavior as Arduino's delay: feeds the watchdog and processes SDK tasks via yield(), keeping WiFi alive. With __delay unreferenced, the linker can now GC both __delay and the original millis function.
